We speculated at the time that people will start creating gamepads, keyboard interfaces, or wireless lighting controls. But it seems Google was already geared up to show off what ADK could do at Google I/O yesterday, and created a giant game of Labyrinth.

When we say giant, we mean it. As you can see in the video, the ball used is actually a bowling ball. The guy at the top of the platform to the right is in control, wirelessly it seems, of the tilting table attempting to navigate around the holes and to the goal.

If nothing else it acts as a great advertisement for what is possible. We’ve seen what people can do with the Kinect motion controller hacking and some unofficial software support, so what is going to appear for a fully supported hardware accessory platform in the future?

The mind boggles as to what hackers will create with this coupling of homebrew hardware and device support. The Arduino platform offers up a great base for pretty much anything you can imagine, and being able to attach that creation to a powerful smartphone or tablet just multiplies the possibilities a hundred fold.

With million of Android device owners around the world this could end up being the equivalent of the App Store for hardware. Make a unique and desirable accessory and you could be laughing all the way to the bank.
